florida gators... never threatened!

If you ain't a Gator, you should be! Alligators (and endangered crocs) are important indicator species atop their food chains, with sensitivity to pollution and pesticides akin to humans. See ESA blawg. Gator blood could be our pharmaceutical future, too. See ESA musing.


Follow the truth.

"This institution will be based on the illimitable freedom of the human mind. For here we are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat it." -- Thomas Jefferson to William Roscoe, December 27, 1820.

Endangered and Threatened Wildlife and Plants; 90-Day Finding on a Petition To List the Mexican Gray Wolf as an Endangered Subspecies With Critical Habitat
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a 90–day finding on two petitions to list the Mexican gray wolf (Canis lupus baileyi) (Mexican wolf) as an endangered subspecies and designate critical habitat under the Endangered Species Act of 1973, as amended (Act). Although not listed as a subspecies, the Mexican wolf is currently listed as endangered within the broader listing of gray wolves. Based on our review, we find that the petitions present substantial scientific or commercial information indicating that the Mexican wolf subspecies may warrant listing such that reclassifying the Mexican wolf as a separate subspecies may be warranted. One of the petitions also requested listing of the Mexican wolf as an endangered Distinct Population Segment (DPS). While we have not addressed the DPS portion of the petition in this finding, we will further evaluate that information during the status review. Therefore, with the publication of this notice, we are initiating a review of the status of the Mexican wolf subspecies to determine if listing the Mexican wolf as a subspecies or DPS is warranted. To ensure that this status review is comprehensive, we are requesting scientific and commercial data and other information regarding the Mexican wolf. Based on the status review, we will issue a 12–month finding on the petitions, which will address whether the petitioned action is warranted, as provided in section 4(b)(3)(B) of the Act.
DATES: To allow us adequate time to conduct this review, we request that we receive information on or before October 4, 2010. After this date, you must submit information directly to the New Mexico Ecological Services Field Office

In August 2009, FWS received petitions from the Center for Biological Diversity, WildEarth Guardians, and The Rewilding Institute requesting that the Mexican wolf be listed as an endangered subspecies or DPS and critical habitat be designated under the Act.   FWS reviewed the petitions and other information, and noted that it showed general agreement that the Mexican wolf is distinguishable from other gray wolves based on morphological and genetic evidence. Currently, Mexican wolves exist in the wild only where they have been reintroduced, and that population has oscillated between 40 and 60 wolves since 2003.  Photo above from the Arizona Zoological Society is one of many wonderful pics available at and the Lobos of the Southwest webpage, sponsored by a collaboration of conservation-minded groups working to protect the species.

Endangered and Threatened Wildlife and Plants; Initiation of 5-Year Reviews of Five Listed Species: Delmarva Peninsula Fox Squirrel, Northeastern Bulrush, Furbish Lousewort, Chittenango Ovate Amber Snail, and Virginia Round-Leaf Birch
SUMMARY: Under the Endangered Species Act of 1973 (ESA), we, the U.S. Fish and Wildlife Service (Service), announce our initiation of 5-year reviews of five listed species: Delmarva Peninsula fox squirrel, northeastern bulrush, Furbish lousewort, Chittenango ovate amber snail, and Virginia roundleaf birch. A 5-year review is based on the best scientific and commercial data available at the time of the review; therefore, we are requesting submission of any such information that has become available since the original listing of each of these species. Based on the results of these 5-year reviews, we will make the requisite findings under the ESA. DATES: To allow us adequate time to conduct these reviews, we must receive your information no later than October 4, 2010.

EXCERPT: Categories of requested information include (A) Species biology, including but not limited to, population trends, distribution, abundance, demographics, and genetics; (B) habitat conditions, including but not limited to, amount, distribution, and suitability; (C) conservation measures that have been implemented that benefit the species; (D) threat status and trends; and (E) other new information, data, or corrections, including but not limited to, taxonomic or nomenclatural changes, identification of erroneous information contained in the list, and improved analytical methods.
